Puerto Rico's governor is vowing to make the U.S. territory the 51st state after statehood won in a non-binding referendum hit by a boycott and low turnout that raised questions about the vote's legitimacy. Gov. Ricardo Rossello told a couple hundred supporters waving U.S. flags late Sunday that he will soon create a commission to appoint two senators and five representatives to demand statehood from the U.S. Congress, which has to approve any changes to the island's political status.
